The Breez SDK: Class of Q3 2026 In Crossing the Chasm, Geoffrey Moore describes the pattern of early adopters on the near side of the chasm, who try something because it’s new, and pragmatists on the far side, who only move when it solves a problem they already have. For most of its life, bitcoin has been a nifty technology on the near side. The Class of Q3 2026 lives on the far side. It includes a hardware wallet that finally spends, a messenger where a payment is just another message, an app to pay utility bills in Romania, a film platform that pays directors by the second, a trailhead coffee shop that knocks ten percent off. None of them are “selling” bitcoin. They’re delivering something people already want, with instant, non-custodial bitcoin built-in, all powered by the Breez SDK. Without further ado, here’s your Class of Q3 2026. BIF Wallet A bitcoin wallet inside Telegram, built for Persian speakers BIFWallet is part of the BIF Ecosystem, built around Bitcoin Rah-e Azadi, a Persian-language community whose name translates to “Bitcoin Is Freedom.” The goal is to go beyond bitcoin education and give Persian speakers practical tools for everyday life. BIFWallet is a non-custodial wallet built directly into Telegram, in Persian, so there’s nothing new to install. The BIF package also includes BIFp2p (a peer-to-peer trading bot) and BIFChat (the community group), which combines education, community, payments, and exchange in one place. It’s bitcoin freedom powered by Breez. BitBox Cold storage, instant spending If you’ve held bitcoin for any length of time, you’ve probably considered a BitBox. Designed and built in Switzerland with fully open-source firmware, it has reliably kept users’ bitcoin on lockdown, which also made that money hard to spend. So BitBox users did what most hardware wallet users do: keep their savings on the device and use a second app for spending, with yet another seed phrase to look after. Now saving and spending both live in the BitBoxApp. Savings stay secured in your BitBox while a spending wallet on your phone handles everyday payments. You can top the wallet up from the device whenever you want. The spending wallet is derived from users’ existing BitBox backups, so there are no new recovery words to write down. The Breez-powered public beta is already on mobile for all BitBox hardware wallets. Bitcoin Pixel Paint by numbers, pay in sats Remember the Million Dollar Homepage? Bitcoin Pixel is its collaborative, pay-as-you-go successor. Pick a banner, draw or import your artwork, place it on the live canvas, and pay a few sats to make it stick. No account, no sign-up, and pixels are repaintable, so the canvas keeps changing as new people paint over the old. Anyone can open a banner, set their own pricing rules, and get paid every time someone paints on it, straight to their own wallet. A full replay shows every change back to the first pixel. Instant bitcoin, powered by Breez. Bro Scan a bill, pay in bitcoin Bro is an open, peer-to-peer way to pay real-world bills in Brazil and across Latin America with bitcoin, with no accounts, no KYC and no central server. Scan a bill or paste a PIX code and pay in bitcoin. A provider on the network pays the bill in local currency and uploads encrypted proof, and once you confirm it’s paid, escrow releases the sats to them. Users skip the exchange, providers buy bitcoin without KYC and earn a 3% fee, and the orders are coordinated over Nostr by coordinators anyone can run. Every user gets a non-custodial wallet powered by the Breez SDK, and Bro already handles PIX, Boleto and TED in Brazil, plus CoDi, PromptPay, Transf 3.0 and Bre-B. BTCfactura The electric bill, paid in bitcoin Bitcoin will have made it when people think of it as an unglamorous utility, like electricity and SWIFT. Well, BTCfactura lets people in Romania pay their electricity, gas, water, and internet bills in bitcoin, across 245+ providers, which is about as unglamorous and useful as it gets. This handy app runs on a self-hosted BTCPay Server through its own fork of Flint, the open-source plugin from Seth For Privacy, that gives every merchant their own wallet with automatic on-chain sweeps. The Breez SDK sits underneath, so the payment clears and the customer gets a receipt in seconds. BuhoGO A community-built wallet that speaks bitcoin BuhoGO is a community-built, non-custodial bitcoin wallet for the web and Android. Either connect it to a node you already run through Nostr Wallet Connect or LNbits, or use the built-in wallet powered by the Breez SDK, and this one app will handle both. The wallet lives on your device, not on anyone’s server, and the code is open on GitHub for anyone who wants to build on it or for it. Coinsnap One wallet, both sides of the counter Most bitcoin wallets specialize in serving either the customer or the shop. Coinsnap, which has built bitcoin payment tools for merchants since 2023, now has one non-custodial app for both: a merchant accepts bitcoin at the register with the same wallet a customer uses to pay, and online shops settle straight into it through a Lightning address set up in the Coinsnap Merchant Dashboard. Over 1,200 people are using it already, mostly in German-speaking countries, but Coinsnap is stoked to be rolling it out across Europe, with instant bitcoin powered by the Breez SDK. Freedomia Spend your bitcoin in seconds Freedomia issues a virtual Visa card with no KYC that can be loaded with bitcoin, USDT, USDC, and a range of other currencies. The current version of Freedomia was born of necessity, and it went live in no time. When their previous swap provider went down, the team rebuilt bitcoin deposits on the Breez SDK in about 23 hours: API key received at 10pm, live by 9pm the next day. Today a deposit is spendable in under 40 seconds, and it works anywhere you can spend with Visa. Freeport.Network A marketplace with no company in the middle Freeport is a peer-to-peer marketplace for rides, services, and goods, and it’s built on Nostr. There is no company in the middle, no server to run, no commission, and no account: just people trading gigs for money without any middleman. The whole app runs from a single HTML file you can download, with an instant bitcoin wallet running on the Breez SDK. Ridesharing is the first use case, and the driver gets paid at the curb with no intermediary getting between the passengers. The next stop on their roadmap is peer-to-peer chat with instant payments. IndeeHub Every second watched is a sat paid Before founding IndeeHub, Zack Mahoney spent half his career in front of the camera and half behind it, so he knows how the video business works. Subscriptions, he says, create distorted incentives that plague the industry, leading to dissatisfaction amongst audiences and filmmakers alike. Blazing a new path, IndeeHub pays filmmakers straight from viewers’ wallets for every second their films are watched, and every viewer holds the keys to their own wallet, letting them watch, tip, or use it as an everyday bitcoin wallet. IndeeHub is in open beta with content by award-winning independents including Dirty Coin, The Ataxian, and Hummingbird. Minmo Bitcoin plumbing for African businesses In Africa, bitcoin on- and off-ramps are often actual human agents who help people buy and sell the bitcoin they need to transact, and Minmo builds the infrastructure that lets businesses offer those services. Leveraging the Breez SDK, Minmo offers three tools, all available through its APIs: hosted wallets for business operations, escrow that holds and releases bitcoin under agreed conditions so swaps between strangers go smoothly, and an OTC desk for pricing, liquidity and settlement. The beauty of bitcoin is its universal applicability, and the beauty of the Breez SDK is adapting that universality to any number of local and regional particularities. Together, Minmo and Breez are fitting the world’s best financial product to the needs of African businesses, and the fit is only going to get better with the stablecoin balances and exportable, accounting-grade records they’re busy building. PPQ.AI Frontier AI is sats away PPQ.AI puts the leading AI models behind one pay-as-you-go interface with no registration and no subscription: send a few sats, get the answer you need, get on with your life. Bitcoin is what makes paying-by-the prompt possible, and PPQ.AI runs its revenue-share payouts through the Breez SDK, so the partners who bring usage to the platform get paid the moment it happens. Radar Chat Chat and send sats to anyone, anywhere Radar is an end-to-end encrypted messenger from the team behind Cake Wallet, with instant, non-custodial bitcoin built in. It’s built on Signal, so your contacts are already loaded, and the payment is a message that settles instantly and stays encrypted along with everything else in the thread. There is no wallet to open and no address to copy. If you lose the phone, a phone number can restore both the account and the wallet. “[The Breez SDK] was fast. No hassle. Easy to use, easy to set up,” says Vikrant Sharma, Radar’s CEO. Just like Radar Chat. Shosho Watch it, zap it, buy it Shosho is a live-streaming marketplace, where fans back the creators they watch and shop their sales without ever leaving the stream. Their latest release adds a non-custodial bitcoin wallet, so viewers can zap a creator mid-show, pay anyone in their contacts, top up streaming server credits, and pay for what they buy, all from the same balance. It’s live now on Android and iOS, powered by Breez. Taro Wallet by DFX Neutral on everything except your keys Taro Wallet is DFX’s open-source, non-custodial bitcoin wallet, and it plugs straight into DFX’s regulated Swiss on- and off-ramp. It features on-chain savings, instant bitcoin, multisig security, and sending and receiving in CHF or EUR, all in one app. Of course, DFX never holds users’ funds. DFX serves more than 30,000 customers and has processed over $100 million in transactions, and its OpenCryptoPay network already takes bitcoin in 137 SPAR stores across Switzerland. With instant bitcoin from the Breez SDK, Taro Wallet is bringing instant payments to everyday grocery shopping in the Alps. Trails Coffee Proof of brew Trails Coffee is a boutique coffee shop located at a trailhead in Anmore, British Columbia, forty minutes from Vancouver, where they roast the trademark Buntzen Blend on site every week. Since opening in January 2026, Trails has built its own app, where every customer gets a bitcoin wallet and their own Lightning address, and orders paid in bitcoin get ten percent off. Buying a cup of coffee has long been the litmus test for bitcoin’s utility as an everyday currency. With Trails Coffee and the Breez SDK, the moment has come, and it’s delicious.

How Agentic Coding Drives Bitcoin Adoption Fifteen years ago, Marc Andreessen wrote that “software is eating the world.” It has. But since 2025, AI has been eating software. Agentic coding, notably since the release of Claude Code, has been radically altering the shape of software development. Projects that used to occupy a team of developers for weeks can now be completed by a single builder in an afternoon at a minuscule fraction of the cost. Bitcoin is no exception. Just as hardware stores are good indicators of construction activity, we at Breez make tools for devs building apps with the help of coding agents and, increasingly, for agents building apps on behalf of humans. Therefore, we see the trends just before they hit the market. The trend we are currently observing and servicing is an unprecedented increase in the quantity of new implementations, the range of apps implementing bitcoin, and the speed with which they hit the market. In short, AI and bitcoin are feeding each other’s rise. Quantitative Transformation: Recent and Huuuge Some changes, like the Industrial Revolution, start gradually and progress incrementally, so it’s hard to date when they really began. The advent of agentic coding is not like that. Claude Code was released as a research preview in February 2025 and became generally available three months later. These dates stand out like beacons in the history of bitcoin’s integration into apps, and they match perfectly with our internal data. The most salient internal data we have is requests from potential partners. Two years ago, we were fielding a steady stream of inquiries from developers who wanted to add bitcoin to their apps with our best-in-class SDK. How many? Enough to keep us busy. Or so we thought. Once Claude Code hit the scene, our steady upward curve pulled back on the stick and hit the afterburner. The volume of inquiries went up 14x, 1400%, ten-ex and a bunch more. Agentic coding has changed the entire development workflow, and since we build tools for developers, our world changed with it. The good news is that we were well equipped to deal with it. By the time agentic coding was becoming a thing, our SDK had been helping businesses add bitcoin to their apps for a couple of years already. We had also just released the implementation leveraging Spark, which is the most scalable tool we’ve ever released. Despite the radically increasing demand, it stood as solid as a pyramid and purred like a kitten under the increased volume. Qualitative Transformation: Here Comes Everybody Beyond the speed and scale of the change, we’ve also noticed two momentous changes in who is inquiring about new partnerships. First, with the advent of Claude Code we started seeing far more inquiries from people who had little to no experience with bitcoin. Prior to 2025, by far the majority of potential partners were orange-blooded bitcoin aficionados, crypto enthusiasts for whom bitcoin was the OG of cryptocurrency, and fintechies who saw bitcoin as just another asset class that belongs in every diversified portfolio. But around the beginning of last year, we started fielding requests from developers building apps from verticals we had barely contemplated. We were getting questions about whether the Breez SDK would work with fitness apps, whether users could send each other money with our SDK in messenger apps, how it would fare as a means of payment in an eSIM service for travel, could the team behind a mushroom-identification app please get a little integration support? (Answers: yes; of course; brilliantly; sure.) The fungus vertical is one few people think about, but which does indicate that one’s SDK has obtained a certain reach. Within a few weeks, our TAM had expanded from maybe one and a half verticals to all the verticals. It’s the “more apps with Lightning” we had been predicting. The second momentous change in the source of the new inquirers was that many were not even human. For example, we’re now regularly fielding requests from coding agents themselves, who are writing on behalf of the companies deploying them. It comes as no surprise that machines are now working with our SDK. It’s a development kit, and they’re designed to help develop software. But the scale is a surprise. Agents and the people using them obviously prefer bitcoin, as our data indicates, but why? AI Tends Towards Bitcoin Because It Has To Both coding agents and human developers building with them need bitcoin, but for slightly different reasons. Many of our new human partners prefer bitcoin for the speed. By the time they’ve opened an account at their local bank and figured out how to deal with cross-border transfers, they probably could have already started turning a profit with bitcoin or stablecoins. Getting ready to accept fiat payments takes weeks, maybe months. With our SDK, you could have become able to send or receive bitcoin, USDT, and USDC from anywhere in the world in about the time it’s taken you to read this far. Take it for a test drive with Glow. For coding agents, speed is just one advantage. Even more important is the fact that bitcoin is permissionless. Agents can build an app and set up its global monetization, letting users send money anywhere at any time, without obtaining anyone’s permission or signing a single form. Bitcoin lets agents build without humans and their petty rules and borders getting in the way. This is a radical departure from the status quo. Conventional payments are built around a world of permission, of humans telling other humans what’s allowed, where, when, and under what conditions. It was a fine system for the days of COBOL and gold reserves. But it is not even wrong when it comes to a world of rapid, global, agentic software development. Bitcoin is agnostic about whether the code of its current owner and user is composed of DNA base pairs or weights in a neural net. AI needs bitcoin because bitcoin accommodates AI. Growth Is Great, Organic or Otherwise Agentic coding is changing bitcoin by vastly expanding the range of apps integrating it into their use cases and by massively accelerating that integration. Conversely, bitcoin is changing AI by giving it a radically new use case: helping developers help users to start moving and harvesting value with unprecedented speed and without the permission and restrictions of traditional financial instruments. There was a time in recent memory when people would ask us whether our tech actually worked. Now they ask how fast they can integrate it. Except that it’s often their coding agents asking us, and the agents answer by implementing bitcoin in seconds. Bitcoin is important infrastructure in the era of coding agents, and infrastructure is what conquers the world. We’re past ideology and orange pills. We’re now at the stage of electrical sockets and subsea cables: parts of the world everybody uses but few really think about (or need to). But for all this rapid change, the fundamental means and ends remain the same. The ends we’re pursuing are just permissionless, global money for all of us. The way to achieve it hasn’t changed either: build products that provide value and make them as simple, seamless, and intuitive as possible. As ever, the user experience is the key, and that remains true even if machines are the ones designing and building it.
